Abstract :
The design, configuration, and performance of a W-band transceiver with a volume of 1 in/sup 3/ is discussed. The transceiver uses a noncoherent chirped waveform for a pulse compression radar application. The authors also discuss a design technique for the local oscillator (LO) of the radar, and the successful demonstration of a Gunn diode LO validating this design procedure. The technique of preheat bias control was demonstrated as a method to compensate the chirp response of IMPATT diode transmitters for ambient temperature variations.<>
